Little more looking into this topic and I find this,
again hosted by Cornell
It's a paper by Giuseppina Nigro and Pierluigi Veltr, and was published by Universit`a della Calabria, Dipartimento di Fisica and Centro Nazionale
Interuniversitario Struttura della Materia.
In particular the model is able to reproduce the dynamical situation in which the large-scale magnetic field jumps between two states which
represent the opposite polarities of the magnetic field, reproducing the magnetic reversals as observed in geomagnetic dynamo and in the VKS
Sounds like they're modeling geomagnetic systems and are beginning to understand the possible mechanics of reversals.
One of the most fascinating and challenging topics in physics and astrophysics is the understanding of the generation and self-sustaining of
magnetic ﬁelds in planets, stars, galaxies, etc. The most accredited mechanism is the so-called dynamo eﬀect, i.e. the maintaining of a
magnetic ﬁeld against diﬀusive eﬀects by the motion of electrically conducting ﬂuid
If the natural dynamo can be understood, could it be replicated in some form? What could you do if you could generate a self-sustaining magnetic
In 1955, Parker  suggested that the net eﬀect of averaging many small scale turbulent motions would be to produce the large scale electric
ﬁeld (α eﬀect) generating large scale poloidal and toroidal magnetic ﬁeld. The latter can also be generated by the diﬀerential rotation
So the magnetic field of the earth, sun, and other stellar bodies all begin life as small perturbations in electrically conductive elements and
propagate out in a synergistic effect producing immense fields from the initial tiny motion.
Could these small scale turbulent motions be caused by the torsion field that is implied as imparting spin to all structure regardless of scale?
The middle graph below represents magnetic reversals (pole shifts). I find it very
reminiscent of the magnetic striping you showed in the OP.
Not that the majority of the reversal happen pretty quickly, that is the line is thin as it switches domains from + to - relatively abruptly. There
are, however, several occurrences as the line traverses the graph horizontally from left to right that the line is very thick, indicating that the
field is both + AND - concurrently.
